3000GT VR4 All Wheel Steering demo

Tested with a 1994 3000GT VR4. AWS is pretty visible in this video when I turn full lock. I turn full lock twice on each side, which is why you see the wheel pop out twice. At around 3/4 of the way through the video I'm jerking the steering wheel back and forth, and you can see it activate then as well.

The AWS system is same phase, meaning the rear wheels turn in the same direction as the front wheels when it activates. The AWS is controlled by a system of valves at the rear differential. There's a valve that limits the AWS to above a certain speed, so it doesn't make parking more difficult. There's also a valve that activates the AWS based on a pressure differential from the two feed lines from the front power steering rack.

The system is extremely stable for lane changes, and helps keep the rear end in check in corners. Professional drivers that have tested the AWS through slaloms say it makes the car feel "different" but they say it's also easier to go faster because the rear end doesn't slide out like it would with no AWS.

Notice the Active Aero front air dam in the video. It pops down at around 48 mph.

Those potenza tyres are crap. Expensive crap. Firestone hawks are the go. .. Made in new Zealand. Try rm.

@seeradog Thanks, but I don't own the VR-4 anymore. I don't even own a car at the moment lol

Thanks for posting this. I have the same car and it does the same thing had I always thought the ass wasn't working properly since you have to be at full lock to se movement. I now know it acts far differently on the ground than in the air but your video helped me out. We now need to get one of those go-pro cameras and point it at the rear wheels while driving through some slaloms or something. That's where the real show would be :)

@weeral1 There's some videos on here of a Stealth set up how you're talking. You can't really see much, unfortunately. It's either not turning, or it's not perceptible on camera.

Today you really don't need 4ws for rear stability. Today active yaw rear torque differential in cars like EVO-10 Super-awd or topline Acura's SH-awd, take place from 4ws stability. But ,Honda's 4ws was more useful during U-turn's, but totally useless in parallel parking.

[DocWalt]

@SANYUR Yeah, the modern yaw control makes a system like this lose a lot of value.

@goldie69 Don't want it rolling away on the jacksta... oh wait.

[goldie69]

lol...handbrake on.

For Active Aero front air dam jump to 0:28

Honda has a better 4WS system. On both the CB7 and Preludes

Sick... Just Sick.

[javaton899]

the renault 12 have a same sistem

@ShinigamiRota weight loss is nice but since the VR4 is front heavy like most cars, removing weight from the front is better...also a good example is relocating the battery to the back because not only are you taking it from the front but adding to the back which balances it out.

[ShinigamiRota]

What your view on the removal system's such as the AWS delete?I know it removes wight but the real reason had to be that the rapid(under speed)left and right(such as s-bend)that can freeze up the steering momentarily. Thus removing the system + the added benefit of weight loss. Woulnd't the trail direction of the car be affected(thinking of the conversation of mitsu heads debating over, its so heavy/but look at the cost all ready ect. so added the AWS.not wllng to buy&try first just want exampl.

[CASSINOx]

it seems kindah delayed.. or is it just me lol

[Predwolf2]

Awesome video, the active aero was pretty damn cool to see!
